Subject: [PATCH] [57/106] x86: Fix a bogus unwind annotation in lib/semaphore_32.S

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Jan Beulich <JBeulich@...ell.com>

commit e938c287ea8d977e079f07464ac69923412663ce upstream.

'simple' would have required specifying current frame address
and return address location manually, but that's obviously not
the case (and not necessary) here.
